Product Description

Designed as an OEM solution, the DTS 307 is unique in that it has one of the smallest foot-prints of any submeter on the market, with dimensions of 3.11”(79mm) D x 4.25”(108mm) H x 1.38”(35mm) W.  Along with a ultra-compact DIN rail design, the DTS 307 requires no external power source to operate and comes with color coded, pluggable connectivity. This meter can function in either a single, split or three phase environment and is equipped with auto-topology detection. It is certified to ANSI C12.20 Class 0.2 (Revenue Grade) providing the most accurate data acquisition available.

The DTS 307 works with all “safe” 333mV current transformers and comes with on-board CT Reverse Algorithms for automatic correction of in-proper field mounted CTs. For remote configurability, all our DTS Series of meters are offered with our free DTS Config software platform; where you can conveniently choose from over 200 parameters at the frequency you require. The DTS Series of meters come with a User-definable Modbus register area. The DTS 307 supports these protocols, Modbus RTU and BACnet MS/TP; additionally, there is a Pulse (kWh) version.

Also, if in the future, you decide to integrate renewable energy sources, the DTS 307 will conveniently operate as a Bi-directional NET meter. The DTS 307 is SunSpec Alliance certified and easily integrates with Building Automation Systems and Energy Monitoring Software. All the DTS Series is designed and manufactured in the USA and complies with the Buy American Provisions of ARRA Section 1605.
